C Au(s) + 3HNO3(aq) + 4HCl(aq) + HAUCl4(aq) + 3NO2(g) + 3H20 (1) AgBr(s) + 2Na2S2O3(aq) - Na3Ag(S203)2(aq) + NaBr(aq) 4Br2(aq) + H2S2O3(aq) + 5H20(1) - 8HBr(aq) + 2H2SO4(aq) 2H2CrO4(aq) —+H2Cr2O7(aq) + H20(1) 3H20(1) + P4(s) + 3KOH(aq) — 3KH2PO2(aq) + PH3(g) Cao(s) + CO2(g) + CaCO3(s) Hg2Cl2(s) + 5HNO3(aq) → 2Hg(NO3)2(aq) + HNO2(aq) + 2HCl(aq) + H2O(1) O 6 KCN(aq) + FeCl3(aq) + K3Fe(CN)6(aq) + 35Cl(aq)

Answer 1

Ansowent oxidation - R 14 Oxidation - Reduction (redox) reactions are the reactions, where one specie undergo oxidation and the other spewe undergo reduction. 1) Aucs) + 3 Htio aq) + 4 HCl (aa) - HAU 3 HNO3 194) + 4 HCl cas HAT Elu lag + 3rd 2 (g) + 36,0 les oxidation - Au Auta Reduction - ats t u Hence True. + - 2) Ag Br is, + 2 ta 232 0 14 Naz Ag ( S. 03/2 cans + No oxidation-reduction Hence false. 3) 4 Br2 (ag) + H2520, can +5Hoces SHBr ruq) + 2H, JO4cars Oxidation sit sto Reduction Br Br +1 - H 1 +2 -2 it Nabrcagi H +2 -2 H -2 H - +1 +6-2 t -2 H- 2H Hence True. +1 +6 -2 +1 + 62 4) 2H₂ 804 199) H₂Cr2O7 (94) +hores No oxidation reduction Hence false. + -2 5 3 How + P4 is) + 41H-2 + 3 KOH(aq) + 3 KH₂PO2 (g) + Piscg) - Reduct on P pt + p 3 oxidahon This types of reachom are called as disproportionation reaction This is a type of redox reaction.
